Help with .NET Sockets C#

[Wife]

Ok. Im trying to create a simple TCP Client / Server. The problem I'm having is with !System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it.

My best bet is that the socket listener is not working, but I could not figure out why. Any help is appreciated. 

public partial class Primary : Form
    {
        public static int port = 80;
        public static TcpListener listener = new TcpListener(IPAddress.Any, port);
        public static Thread conn = new Thread(awaitConnection);

        static void awaitConnection()
        {
            listener.Start();
            listener.AcceptSocket();
            MessageBox.Show("New Connection received.");
        }

        public Primary()
        {
            InitializeComponent();
        }

        private void Primary_Load(object sender, EventArgs e)
        {
            conn.Start();
        }

        private void toolStripStatusLabel1_Click(object sender, EventArgs e)
        {

        }
    }

and

 class Program
    {
        public static TcpClient client; 
        public static int port = 80; //Connection port
        public static string ipaddress = "25.52.118.139"; //Connection IP Address

        static void Main(string[] args)
        {
            client = new TcpClient();
            try
            {
                do
                {
                    client.Connect(IPAddress.Parse(ipaddress), port); 
                    //Establish and maintain connection until it's no longer available.
                } while (client.Connected != true);
            } catch(Exception err)
            {
                Console.WriteLine ("Error!" + err);
            }
        }
    }
